Vortex Analysis of Intra-Aneurismal Flow in Cerebral Aneurysms

Figure 6

Comparison of identified vortex cores from the four mentioned methods: (a) standard , (b) [normalized] , (c) standard -criterion, and (d) [normalized] -criterion. Top row is from SA2 case, and bottom row is from the TA1 case. Velocity streamlines were added to represent simulated flow patterns. Geometries of SA2 and TA1 can be found in Figure 2. Threshold values for each case were the mean (for their representative value), and only extracted vortex cores with a volume > 0.5 mm³ are shown. Figures are from each method’s vorticity averaged data.
